Document Type and Number:
WIPO Patent Application WO/2021/229322
Kind Code:
A9
Abstract:
Disclosed in the present invention is a vehicle braking system comprising an accumulator (40), the accumulator (40) comprising: a cylinder (410), provided with a first end portion that defines a fluid port (412); an end cover (450), mounted on a second end portion of the cylinder (410) and together with the cylinder (410) defining a piston chamber (430) in communication with a fluid of the fluid port (412); and a piston (440) accommodated in the piston chamber (430) and able to move back and forth in the axial direction therein. An elastic element (460) is clamped between the piston (440) and the end cover (450), the piston chamber (430) is divided by the piston (440) into a high-pressure side in communication with the fluid of the fluid port (412) and a low-pressure side where the elastic element (460). The accumulator (40) further comprises a drain hole (499) configured to be used to guide brake fluid that has leaked from the high-pressure side in the piston chamber (430) to the low-pressure side of the piston chamber (430) away from the low-pressure side. The present invention further relates to an accumulator for the vehicle braking system.
